Chemical industry waste streams are most often derived from several sources: process discharge; cooling water (recirculated or nonrecirculated); and boiler water blowdown or boiler water conditioning treatments. Pollution is measured by the product of concentration and flow. Before one can submit ...
What is salinity? Put simply, it refers to the ‘saltiness’ of a given body of water. It is the concentration of dissolved mineral salts therein — and is often measured either directly by its concentration or through electrical conductivity, which it affects. But let’s take a closer look...
Hardness in water can indicate high concentrations of calcium, magnesium and other dissolved minerals. In general, this includes 120-180 ppm of iron, calcium and magnesium, or at least 61 milligrams per liter or higher of calcium carbonate concentration. While magnesium and calcium are essential fo...
Water boarding as it is currently described involves strapping a person to an inclined board, with their feet raised and their head lowered. The interrogators bind the person's arms and legs so no movement is possible and cover the person's face. In some descriptions, the person is gagged,...

If 6.00 mL of a 1.248 M solution of NaCl was poured into 12.0 mL of distilled water, what is the concentration of the resulting solution? Dilution: Dilution is a common or usual technique performed in the laboratory that lowers the...
Water hardnessis quantified by the concentration of calcium and magnesium ions in the water. Minerals consist of atoms, or molecules, that are bound together because they have opposite electric charges. Atoms, or molecules that are charged, are calledions. A mineral consists of a positive ion,...
there is a need to monitor the concentration of oil in water. In shipping, oil-in-water monitors are needed for compliance with ballast water and bilge water discharge standards. In oil and gas production, oil-in-water technologies are used to ensure that separation is as effective as possibl...

Evaluating How Hard Water Is According to the USGS, the hardness of water is determined based on the concentration of dissolved multivalent cations: soft water - 0 to 60 mg/L (milligrams per liter) as calcium carbonate moderately hard water - 61 to 120 mg/L ...
